Install a hard disk in an external caddy

There are several reasons why you may want to fit a hard disk in an external box like this one here. It’s a good way of moving files from an old computer to a new one without opening the case of the new computer.

Alternatively an external hard disk is a good place to put backups or a way of transferring large files between computers.

Buying a case, sometimes called a caddy, and a hard disk separately means you can select the kind and price of hard disk. Be careful to buy equipment that uses the same connection technology. Hard disks come in two flavours, Pata like the one in our video or the new Sata type. You may need a Pata caddy for older drives, otherwise always go for Sata.

Also think about the connection on the back. USB is found on just about every computer, but if you are going to be transferring large numbers of files, an eSata socket can also be very useful. This gives the drive the same quality of connection as if it was installed inside the computer.

To install the hard disk. Open the caddy and remove the hard disk from its packaging. In this case the hard disk is mounted on a separate board so remove this from the caddy. Fit the hard disk and carefully line up the connections at the back.

Once it's in place fit the four screws that hold the drive. Replace the board in the caddy, make sure it is fitted firmly and all the ports line up. Then fit the lid and the final screw that holds the lid on.

If the hard disk came from an old computer, using it will be as simple as plugging it in and waiting for Windows to install the software. If the hard disk is new, it will need preparation to work. You can see how by watching our video on how to prepare a new hard disk for use with Windows.
